IMPROVEMENT IN SULKV-PLOWS.

Specification forming part of Letters Patent No.

190,652, dated May 8, 1877; application filed January 13, 1877.

To all whom it may concern:

Be it known that I, WILLIAM S. WEIR, of Monmouth, in the county ofWarren and State of Illinois, have invented certain new and usefulImprovements in Sulky-Plows; and I do hereby declare that the followingis a full, clear, and exact description thereof, which will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawin gs, and to lettersof reference marked thereon, which form a part of this specification, inwhich- Figure 1, Sheet 1, is a rear elevation of a sulky-plow embodyingmy invention. Fig. 2 is a perspective View, partly broken away. Fig. 3is a detail perspective view. Fig. 4, Sheet 2, is a rear elevation. Fig.5 is a side elevation, near wheel, in dotted lines. Fig. 6 is a detailperspective view, showing the main part of the axle. Fig. 7 is anenlarged view of one end of the axle and the sliding plate which carriesthe wheel. Fig. 8 is a transverse section of the axle in the line a; asin Fig. 6.

The nature of this invention relates to sulky-plows, or plows having aseat for the operator and a carriage attachment; and the inventionconsists in the use of compound levers for suspending the plows upon thecarriage when not in use, and also in the manner of securing thefurrow-wheel to the axle.

Referring to the drawings by letters, letter A represents the axle, itsupper portion a formed of wrought channel-iron, or iron having a webwith two flanges, as shown at Fig. 8, its side vertical portions a aformed of malleable iron, similar in their cross-sections to the part a,but with the addition of feathers a on their outer corners. The part ais also formed integral with a quadrantal rack-bar, B, on its upper end.The parts a a are bolted or otherwise secured to the bar a.

O is the land-side wheel, and O the furrow-wheel, each journaled onspindles c c, which are fixed'to sliding plates D D, respectively,having grooved edges fitting overthe feathers a, on which they may beadjusted in higher or lower planes. The plate D is operated by ane1bow-lever,E, pivoted to the lower part of the quadrant B at d, and

has a spring-pawl, d, which engages with the rack B. The lower end ofthe lever E is connected by a link, 0, with the plate D. The plate D hasa projecting boss, f, around an aperture in its upper end, and the bossf is slotted down one side for the reception of a detent,f, whichprojects from one side of the bolt F. The bolt F may. thus be insertedthrough the aperture in the plate D, and made to engage with any of aseries of holes, 8, in the bar a, when, by turning the detent f into arecess made for it in the boss f. the bolt F and plate D may be securelylocked in position, as shown more plainly by the enlarged view at Fig.7. By these means the plate D may be secured readily, easily, and firmlyin a lower position on the axle, as shown at Figs. 2, 4:, and 7, and bydotted lines at Fig. 5, or in a higher position, as shown at Fig. 1, orin various positions, as required to retain the bar a in a horizontalposition while the wheel 0 is the depth of the desired furrow lower thanthe wheel C.

G is the plow, to the forward end of which the team is hitched. H is adouble crank or yoke, the ends or shafts h of which are journaled in andnear the lower ends of the bars a a, and the sides or webs h of whichextend back, and are connected to form a wrist, h", on which a plate orsaddle, I, is mounted by means of eyebolts or loops, i, so that it maybe oscillated thereon in a vertical plane at right angles to the wristh. J is a yoke, by which the plow-beam G is bolted to the saddle I,further security of attachment being secured by lugs 42.

K is the guide-pole, mounted on the bar a. L is a bell-crank lever,suitably journaled at its angle to the pole K, and its longer armprovided with a spring-paw], l, which engages with a rack-bar, M, fixedto the side of the guide-pole K. The lifter for the pawl l is abell-crank lever, l, fulcrumed at its apex to the distal end of the longarm of the lever L,

its short arm attached to the upper end of the connecting-rod to thepawl l, and its longer arm having a notch, 1, into which a detentlink,l, may be turned, as shown by dotted lines at Fig. 5, for the purpose ofholding the pawl l disengaged from the rack-bar M when desired. N is alever, fulcrumed in standards n, which project upward from the bar a,the longer arm of which projects forward, and is connected by a link. 0,to the short arm of the lever L, and the short arm of which projectsrearward, and is connected by a link, P, to the distal end of the doublecrank B.

Q is the operators seat, secured by a standard and spring above the bara.

The wheel 0 maybe adjusted on the bar a to regulate the depth ofplowing.

The intermediate connections between the lever L and the double crank Hare such that when the lever L is thrown well back, and locked by thepawl l to the rack-bar M, as shown by full lines at Figs. 1, 2, 4, and5, it will act as a lock to crank H, making a rigid connection therebywith the axle A, and allowing the weight of the carriage and driver, orany desired portion thereof, in proportion as the lever L is adjusted onthe bar M, to be thrown on the plow, and on a rolling cutter or otherdevice attached thereto.

When it is desired, in plowing in rough ground, 850., to allow the wheel0 to rise and fall to pass over small obstacles without disturbing thelevel of the plow, the link l' may be engaged with the notch l, andthus, holding the pawl disengaged with the rack-bar M, permit ofmovement vertically of said wheel and independently of the plow.

For raising the plow clear of the ground, for local transportation onits own carriage, the lever may be thrown forward, as shown by dottedlines at Fig. 5.

The lever E may be used for leveling up the axle temporarily in case ofirregularities of surface of the soil, &c.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- 1. In combination with the axle A andyoke H, to which the plow is secured, the doubleelbow lever L, link 0,lever N, and link P, the lever N being pivoted to the axle, and thewhole arranged in close proximity thereto, substantially as and for thepurpose specified.

2. The bolt F, having a detent,f, arranged to operate with the slidingplate D, constructed as described, and with the perforated plate a,substantially as and for the purpose specified.

In testimony that I claim the foregoing as my own I aflix my signaturein presence of two witnesses.

WILLIAM S. WEIR.
